Abstract
The utility model discloses a bicycle with a spare tire, which has routine parts of a normal bicycle with a framework, handlebars, a front fork, chain wheels, a central shaft, a cycle chain and a fly wheel, and is characterized in that a layer of antiskid rubber is fixed inside a steel ring of the rear wheel; one end of a telescopic bracket is mounted on a steel pipe of the frame close to the rear wheel shaft, while the other end is connected with a rotating shaft of the spare tire; the spare tire consists of an inner wheel and an outer wheel which are coaxially fixed; the spare tire is far away from ground and is not contacted with wheels when the bracket is folded. When the bracket is extended, the inner wheel of the spare tire leans against the antiskid rubber inside the steel ring to transfer rotation. Therefore, the outer wheel of the spare tire leans against the ground and replaces the original wheel.
Description
Technical field
The utility model relates to a kind of bicycle, especially a kind of bicycle of preparing and carrying tire.
Background technology
Bicycle is the Personal Transporter who uses always, the current fitness tool that more becomes a kind of environmental protection fashion, by bike the time, the often stressed big and fault such as be easy to occur blowing out of trailing wheel, and bicycle does not in the market generally have spare tyre, and some child's bicycles have two small wheels to play to help the effect of infantile study car at trailing wheel, but can not real at last spare tyre, because its position and altitude hold can only be played a supporting role once in a while.The utility model has really realized preparing and carrying the bicycle of tire easily, and does not influence the original actuating speed of bicycle when using spare tyre.
Summary of the invention
A kind of bicycle of preparing and carrying tire, conventional part such as the skeleton of bicycle, handlebar, front fork, sprocket wheel, axis, chain, flywheel is the same with ordinary bicycle, it is characterized in that: the steel ring of trailing wheel is slightly wideer than the steel ring of existing bicycle wheel, the inboard fixedly one deck anti-slip rubber of steel ring, there is a telescope support one end to be installed on the skeleton on the steel pipe near hind axle, the other end is connected with the spare tyre rotating shaft, and spare tyre is made up of wheel and foreign steamer in co-axially fixed.Spare tyre is away from ground and do not contact with wheel during the support condensation, and the support elongation then makes the interior wheel of spare tyre be against on the anti-slip rubber of wheel steel ring inboard and transmits by this and rotate, and the foreign steamer of spare tyre was against and substituted original wheel on the ground this moment.
Beneficial effect: the utility model is simple in structure and firm, and productive costs control is better, the emergency handling under the situation of blowing out when greatly having made things convenient for cycling, the safety that has improved cycle touring.
Description of drawings
Fig. 1 is a kind of bicycle structure scheme drawing of preparing and carrying tire of the utility model example.
Fig. 2 is that the utility model example does not use spare tyre effect scheme drawing.
The specific embodiment
The explanation of mark among Fig. 1: skeleton 1, trailing wheel 2, steel ring 3, anti-slip rubber 4, telescope support 5, spare tyre 6, foreign steamer 7, interior wheel 8.
A kind of bicycle of preparing and carrying tire shown in Figure 1, the steel ring 3 of trailing wheel 2 is slightly wideer than the steel ring of ordinary bicycle wheel, steel ring 3 inboard fixedly one deck anti-slip rubbers 4, there are a telescope support 5 one ends to be installed on the skeleton 1 on the steel pipe near hind axle, the other end is connected with spare tyre 6 rotating shafts, and spare tyre is made up of co-axially fixed foreign steamer 7 and interior wheel 8.
Referring to Fig. 1, when faults such as blowing out appears in trailing wheel 2, support 5 elongations offset the interior wheel 8 of spare tyre and the anti-slip rubber 4 of steel ring 3 inboards, foreign steamer 7 with bicycle rear 2 supports overhead, under the friction force effect, the rotation of trailing wheel 2 sends the interior wheel 8 of spare tyre 6 to, and interior wheel 8 drives foreign steamer 7 by axle and rotates with same cireular frequency.This moment, spare tyre 6 alternative trailing wheels 2 advanced bicycle.
Referring to Fig. 2, spare tyre 6 is away from ground and do not contact with trailing wheel 2 during telescope support 5 condensations, and the bicycle cruising is not subjected to the influence of spare tyre 6.
